International Doom

International Doom is a small, functional and simple source port, created with help, efforts and bits of code from people around the world. Initially it was started in 2016 as translation-only project, but further development was inspired by Crispy Doom and Doom Retro source ports (and continued with extensive support from their authors - Fabian Greffrath and Brad Harding).

International Doom was previously known as "Russian Doom", but was renamed in response to the.
